BOX MOTION FOR LOOKS.

Application filed August 31, 1927. Serial No. 210,5 3,

Hutchins Patent No. 551,104. Usually the movements of said mechanismdepend on a (lobby. 1 Where the loom contains a jacquard machine it isdesired to make such movements depend on the callofhooks in thatmachine. But heretofore this has not been accomplished without certaintroublesome complications. According to the present invention theselection or calling is effected from pattern-controlled hooks orequivalent of a jacquard machine (or it may he a (lobby) whereas theactual movements of the vibrator mechanism are effected by an actuatoroperated by ging means in the loom; This in itself is not new. But it isnew and is a feature of my invention that the actuator transmits the amovement from the going means to the vibrator mechanism directly and notthrough means movable independently of the latter.

In the drawing,

Fig.1 is a side elevation of a loom embodying the invention;

Figs. 2 and 3 are a rear and side elevation, respectively, of certain ofthe principal parts of the invention one. larger scale; and

Fig. 4 is a fragmentary rear elevation of a detail. a 1 a a The loomframe 1 lifte1fr0d 2 for the boxes 3; the lever 4 to which thelifter-rod is connected; the bell-crank leversh fulcrumed in theloom-frame and connected by links 6 to diflerentpoints in the length ofand thus supporting lever 4:; the vibrator-gear connectors 7 thevibrator-gears 8 to an eccentric point of each of which one suchconnector is pivoted and each of which is journaled in a vibrator-lever9 fulcrumed in the frame; the mutilated cylinder gears 10 formed withgears 10 and forming a part of a gear-train including the transmissiongears 11 and 12; the gear 13 from which such train is driven; and thedetent device 14 controlled by a cam 15 and serving to lock avibrator-lever in either position to which it is shifted (with itsvibrator-gear in mesh with or Operative crank lever formed with relationto one or the other of the cylinder gears) are or may be all the same asusual.

The vibrator mechanism movable to be actuated by the goingmeans isheremade to include, with each s *stem of parts 7, 8 and 9, anupstanding mem er (incidentally forming a guide) 16 connectedto lever 9andwhich, if it is a wire or otherwise flexible, maybe held taut by alever 17 weighted at 17" but not so as to balance or overbalancelever 9;said member has afixed to it a block 18 in which is pivoted acatch-device 19,0!- belldepending arm.

when the vibrator mechanism is moved up a notch 19? in its or down, sothat gear 8 m s sv h PP orlower gear 10, said mechanism is actuated bythe going means, 1. e ear 8 lsturned one way or the. other to shiit thebox structure and comes to a dwell,all in a characteristic way and wellknown; in the present case this nioving'of saidmechanism in the upwarddirectiondepends on upward movement of its member 16, its downwardmovement being due to allowing member 16 to fall and to 1 the action ofgravity on said mechanism.

Sliding on member 16 as a guide is an actuator comprising a block 20havm a projection or toe 20 to engage in note 19 of the catch-device anda link22 connecting the block with a wrist-pin 21 which is set close tothe axis of one of the gears in the geartrain, as 12. y

Thecatch-device is patterncontrolled, as p a by being connected to a.leverstructurmgenerally denoted by 23 and fulcrumed at the top of theloom frame, by a link 24, which lever structure is in turn connected,bya link 25,

with one of the hooks 26of a jac uardmachine, whose rising and fallingis shown at 27. Each lever structure here comprises a shaft 23 andcranks 23", 23 thereon to which the links 25 and 24 are respectivelyconnected.

boxes at the near side of the loom and the other two of which appertainto such a lever (not shown) as 4 for the boxes at'the other side.

Operation: lVhile the going means is operating the actuator will beconstantly reciprocated. Assuming any one of said vibrator mechanisms tobe in either of its positions for actuation by one of thecylinder-gears, on each rotation of the mentioned gear-train detent 14moves to unlock lever 9 and permit said mechanism to shift to its otherposition. It said mechanism has been positioned for actuation by thelower cylinder-gear and a call comes from the corresponding hook 26 forit to be moved to position for actuation by the upper cylinder-gear the2ll3Cl1tlVlC(-3 will couple said mechanism with the actuator on thelatters next ensuing rise and said mechanism (being unlocked for thepurpose, as stated) will shift to the upper position. It will remain,etl'ect-ively, in that position until the hook 26 allows thecatcludevice to retract or assume the ui'icoiuiling position that is tosay (assuming said mechanism is to remain now unactuated for more thanone rotation of the cylinder-gears), whereas it will of course 7 falleach time the de'tent moves to unlockino a position, it will be at oncereturned by the actuator and (until the teeth oi the cylindergears haveswept past) stand locked by the detent in the upper position. In short,the vibrator mechanism functions the same as it does in all box-motionscharacterized by such a mechanism except that when the vibratormechanism is to remain operative with respect to the upper cylinder-gearfor more than one pick of the loom it falls to the lower position and isreturned to the upper position in the intervals between those periods inthe cycle of rotation of the cylinder-gears when their teeth arepresented to, or sweeping past, the vibrator-gear.

In my construction the catch-device acts to transmit movement from theactuator to the vibratoraneehanism directly; in any previous boxoperating system of which I know and in which the selection isaccomplished from the jacquard machine of the loom and the shiftingeffected by going means a catchdevice has shifted a means (as in anindicator) movable step by step to obtain the two positions of saidmechanism, which means was thus an intermediary between the catchd'ericeand the (reciprocal-cry) vibratory mechanism.

I claim:

1. In a shuttle-box motion for looms, the combination, with going meansincluding spaced mutilated gears and with vibrator mechanism movableback and forth from one to the other gear to be actuated thereby andnormally urged toward one gear, of a constantly going actuator movedback and forth by the going means and from which to move said mechanismtoward the other and a pattern-controlled catch-device movable into andout of position to transmit such movement from the actuator directly tosaid mechanism on movement of said actuator in one direction and carriedby one of them.

In a shuttlebox motion for looms, the combination, with going meansincluding spaced mutilated guns and. with vibrator mechanism movableback and forth from one to the other gear to be actuated thereby andnormally urged toward one gear and having a guide, of a constantly goingactuator n' oved back and forth by the going means and guided by saidguide and from which to move said mechanism toward the other gear, and apattern-controlled catclrdevice movable into and out oi position totransmit such movement from the actuator directly to said mechanism onmovement of said actuator in one direction.

3. In a shuttle-box motion for looms, the combination, with going meansincluding spaced upper and lower mutilated gears and with vibratormechanism movable up and down from one to the other gear to be actuatedthereby and normally urged downward and having an upstanding flexibleguide movable up and down therewith and means to hold the guide taut, ofa constantly going actuator moved back and forth by the going means andguided by said guide and from which to move said mechanism upward, and apattern-controlled catch-device movable into and out of position totransmit such movement from the actuator to said mechanism on movementof said actuator in one direction.
